- NECK-YOKE.

SPECIFICATION forming part of Letters Patent No. 728,033, dated May 12, 1903.

Application filed March I1, 1903- Serial No. 147,333. N model-J To all whom it may concern.-

Be it known that I, ROBERT W.'SPARKS, a citizen of the United States, residing atNevins, in the county of Clark and State of Wisconsin, have invented certain new and useful Improvements in Neck-Yokes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in neck-yokes, and particularly to the provision of a neck-yoke compris-' ing a straight shaft either solid or hollow and provided with spring-arms which are secured adjacent to the ends of the shaft and carry stirrups at their inner ends, which stirrups are mounted over the shaft and are engaged by'the poleof the vehicle.

The invention consists, further, in various details of construction and in combinations and arrangements of parts, which will be hereinafter fully described and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which drawings- Figure 1 is a perspective view of my improved spring neck-yoke, and Fig. 2 is a detailview showing the stirrups and ring detached.

Reference now being had to the details of the drawings by letter, A designates the shaft of the neck-yoke, which may be either of metal or other material and either hollow or solid. Fastened to the ends of said shaft are the rings B, which are adapted to be connected to the harness of a team, and O O. designate spring-bars, whichare fastened at O at their outer ends to the ends of said shaft, and the free ends of said bars are held adjacent to each other and near the middle of the shaft. The inner end of each of said bars is turned into a rollD, forming a bearing for a pin E,.and F F- designate stirrups the ends of whichare apertured and mounted on said pivotal pins, and portions of each stirrup are bent to form loops K, designed to be engaged by a ring L, which is adapted to to be mounted on the pole-tip.

From the foregoing it will be observed that by the provision of the spring-bars with-stirrups mounted as described a yielding movement is allowed in case a team attached to the pole-tip should come suddenly to a standstill or would attempt to stop the advancing vehicle suddenly, thus causing the vehicle to come gradually to a standstill.

While I have shown aparticular construction; of device embodying the details of my invention, it will be understood that I may make alterations in the detailed construction of thesame without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A neck-yoke comprising a shaft, rings secured at the ends thereof, spring-bars secured to the ends of said shaft, stirrups secured to the inner yielding ends of said bars, and a ring connected to said stirrups, as set forth.

r. 2 A neck-yoke comprising a shaft, rings secured to the ends thereof, spring-bars fastened at their outer ends to the ends of said shaft, the inner end of each bar being turned of each stirrup being bent to form a'loop, and

a ring engaging said loops, as set forth.

In testimony whereof -I hereunto affix my signature in presence of two witnesses.

ROBERT W. SPARKS.
